dumpstate: Add "MODULES INFO"

Print .modinfo of each kernel module in section "MODULES INFO". Size of
modinfo for a module is usually 200 ~ 500 bytes. The number of kernel
modules of product with GKI enabled can be 200+, so this could add
extra 100 KB to bugreport in such case.

Bug: 186171455
Test: Take bugreport and check outputs
